I was on the Helm Inc. website looking for a service manual for my 2004 GXP. I see they have the Bonneville Service Manual. I am guessing it would cover the GXP, however, I would hate to spend $135 and find out when I get the manual that it does not cover the GXP. Can anyone confirm that this manual covers the GXP??

you might want to PM JimmyFloyd , he had a set of 2004 manuals for sale., and for much less than $135..

I have a set for $2004. I was looking to get $100/BO shipped for them. I'll check them when I get home and let you know.

If it is a '04 service manuel it should definately cover the gxp. If you want to save money, I would suggest a subscription to alldata. I purchased a 3 yr. 04 gxp subscription manuel on line for 30 dollars for the complete 3yrs. and it has been very benificial.
